Small Engines (Lawn Mowers, etc.): old craftsman snowblower, craftsman snowblower, snow blowers

Question
Eric,
thanks for the pointers on the carb. i havent had a chance to try it yet but maybe this weekend. i have been trying to get back to you for a few days but your mailbox has been full. about the drive, yes i can turn the wheels by hand although it is hard. i have been all over the drive system and fully understand how the gear reduction works and also the "transmision wheel". the machine did not stall when the auger was ingaged, only when it was put into any drive.

Hi Eric,
    The model number is 536906300, the registration number is 7216 and the motor number is 675062 ser 7181D.    
    I hope this helps you out.  I couldn't find any label as to what kind of carb or engine it is but any information you have to adjust the carb or get it back to running condition will be much appreciated.

eric,
i just got an old crafstman "eager-1" 5-24 snowblower from a friend. it didnt take much to get it running, cleaned out the fuel tank, changed the plug and it fired right up. after figuring out why the transmission wasnt working, that is when i found out that it dies after being put into any drive gear. i check all the pin/kill switches and even disconnected them. when you engage drive it moves for about 3 feet before it dies. what do you think?

-----Answer-----
Is the drive system malfunctioning causing too much load on the engine causing it to die?

As you stated earlier, if the safety switches, "kill" devices are not working correctly the engine will die.  Usually the engine will die imediately if a safety switch is not working correctly.

What is the model of the snowblower.  The number will be located on the frame...not on the engine.  Let me know so I can look up some information.

The engine is a Tecumseh engine; standard on many snow blowers.  The carb is pretty standard as well.  Turn the adjustment screws in until they GENTLY seat.  Use your fingers or a small screw driver.  OVER tightening them will ruin the taper point tip and can damage the carb.  Turn both needles out 1 1/4 to 1 1/2 turns for initial setting.  Run engine to high speed.  Turn bottom needle out until engine rpm drops and the engine runs rough.  Then turn needle in just until the engine runs smooth.

Idle the engine to 1800-2000 rpm.  Use the same technique on the side (idle/air) adjustment needle.

Can you turn the drive wheels by hand?  Will the auger turn without stalling the engine?
Let me know.

Answer
There may be something binding in the drive system causing too much load on the engine.  Also, it is possible the engine is wore and not producing enough power.

I would inspect the drive system and lube/clean all the parts.  Can you tell if the engine is running fast enough? A tach is very helpful for determining engine speed.
Let me know.
Eric
